Problem with tempotec Sonata Dac

Recently i bought a Tempotec Sonata HD Pro USB Dac to use with my Ropieee.

Ropieee and Roon recognize the Dac, but after some time the connection is lost and i need to install the Dac again.

Today I installed Dietpi with Roon bridge and the Sonata Dac works perfectly.

Can someone explain to me why Ropieee has problems with this Dac?
